ABSTRACT

The present application is directed to composition comprising various maca extracts and the use of such compositions for treating certain diseases, disorders, and conditions.

INCORPORATION BY REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. application Ser. No. 15/654,440 filed Jul. 19, 2017, which claims priority to U.S. Provisional Application No. 62/411,977 filed Oct. 24, 2016, the contents of which are incorporated by reference herein in their entirety.

BACKGROUND

The present disclosure relates to novel compositions of maca root (Lepidium meyenii, also called Peruvian Ginseng) and methods of using same. Such compositions may be used, for example, in improved methods of increasing libido, ameliorating sexual dysfunction caused by antidepressants, decreasing inflammation, increasing energy levels, increasing stamina, increasing athletic performance, improving memory, ameliorating discomfort related to menstruation, ameliorating the symptoms of hormonal imbalances, HIV/AIDS, cancer (including discomfort due to administration of chemotherapy to treat cancer), menopause, andropause, anemia, osteoporosis, and chronic fatigue syndrome, improving fertility, decreasing symptoms of tuberculosis, improving mood (for example, reducing depression), and increasing immune function.

More particularly, the present disclosure relates to the surprising and unexpected finding that particular combinations of maca root varieties are more effective than other maca root varieties, alone or in other combinations, at reducing inflammatory markers, such as cytokines, and thus may likely be more effective and/or provide more beneficial results to subjects ingesting the compositions disclosed herein than previous maca root containing products.

Maca is used as a food, similar to sweet potatoes, but also has a number of medicinal properties. Traditionally, maca is processed by boiling, baking, and drying the root, and then grinding the dried root material into powder. Various maca root powders are commercially available. Fresh maca roots have different colors due to genetic variations that result in different phytochemical profiles in the different maca phenotypes. The different genotypes, reflected in root color phenotype include yellow, red, purple, blue, black, and green. Yellow maca is the largest and sweetest-tasting, and are most commonly grown for food, while red and black maca are generally considered more medicinally potent, for example, to reduce inflammation.

Inflammation is part of the non-specific immune response that occurs in reaction to bodily injury. Cytokines, amongst other factors, are regulators of the inflammatory process. Cytokines are small, secreted proteins with a specific effect on the interactions and communications between cells. There are both pro-inflammatory cytokines and anti-inflammatory cytokines.

Interleukin 6 (IL-6), for example, has broad physiological effects, including both pro- and anti-inflammatory properties, depending on the biological context. IL-6 is implicated in numerous disease processes, including chronic inflammation, diabetes, and rheumatoid arthritis. While IL-6 is a promising target for clinical intervention, its complicated signal transduction pathway makes such intervention challenging.

Inflammation can also lead to sexual problems (or sexual dysfunction). These conditions are widespread and adversely affect mood, well-being, and interpersonal relationships. Most sexual problems relate to sexual desire (libido) in both females and males and male erectile dysfunction (ED). Current pharmacological interventions for the management of sexual problems include drugs, intrapenile therapies, and penile prosthesis implantation for males and hormonal therapy for females. Treatment of sexual problems in females is also problematic, with pharmacological treatments often resulting in severe, undesirable side-effects. Non-pharmacological treatments include vaginal electromyography biofeedback, pelvic floor physical therapy, cognitive behavioural therapy, transcutaneous electrical nerve stimulation, and vestibulectomy. Post-menopausal women may also suffer from decreased libido, in part due to falling estrogen and testosterone levels. Decreased libido remains a significant sexual problem in both males and females.

SUMMARY

This application is based in part on the surprising discovery that certain maca root blends provide an unexpected increase in the reduction of the anti-inflammatory response of cells. In some aspects, the maca root blends can be used to treat, ameliorate and/or prevent inflammatory responses. In some aspects, the maca root blends, disclosed herein, may be used to increase libido and or to treat, ameliorate, or prevent symptoms of sexual dysfunction. After considering this discussion, and particularly after reading the section entitled “Detailed Description” and the attached appendix (Appendix A, which is herein incorporated by reference in its entirety), one will understand how the features of the compositions and methods disclosed herein provide advantages over other known compositions and methods.

Controlled release vehicles are well known to those of skill in the pharmaceutical sciences. The technology and products in this art are variably referred to as controlled release, sustained release, prolonged action, depot, repository, delayed action, retarded release and timed release; the words “controlled release” as used herein is intended to incorporate each of the foregoing technologies.

Numerous controlled release vehicles are known, including biodegradable or bioerodable polymers such as polylactic acid, polyglycolic acid, and regenerated collagen. Known controlled release drug delivery devices include creams, lotions, tablets, capsules, gels, microspheres, liposomes, ocular inserts, minipumps, and other infusion devices such as pumps and syringes. Implantable or injectable polymer matrices, and transdermal formulations, from which active ingredients are slowly released, are also well known and can be used in the disclosed methods.

Controlled release preparations can be achieved by the use of polymers to form complexes with or absorb the maca. The controlled delivery can be exercised by selecting appropriate macromolecules such as polyesters, polyamino acids, polyvinylpyrrolidone, ethylenevinyl acetate, methylcellulose, carboxymethylcellulose, and protamine sulfate, and the concentration of these macromolecule as well as the methods of incorporation are selected to control release of active complex.

Controlled release of active complexes can be taken to mean any of the extended release dosage forms. The following terms may be considered to be substantially equivalent to controlled release, for the purposes of the present disclosure: continuous release, controlled release, delayed release, depot, gradual release, long term release, programmed release, prolonged release, programmed release, proportionate release, protracted release, repository, retard, slow release, spaced release, sustained release, time coat, time release, delayed action, extended action, layered time action, long acting, prolonged action, sustained action medications and extended release, release in terms of pH level in the gut and intestine, breakdown of the molecule and based on the absorption and bioavailability.

Hydrogels, wherein maca powder is dissolved in an aqueous constituent to gradually release over time, can be prepared by copolymerization of hydrophilic mono-olefinic monomers such as ethylene glycol methacrylate. Matrix devices, wherein maca powder is dispersed in a matrix of carrier material, can be used. The carrier can be porous, non-porous, solid, semi-solid, permeable or impermeable. Alternatively, a device comprising a central reservoir of maca powder surrounded by a rate controlling membrane can be used to control the release of the complex. Rate controlling membranes include ethylene-vinyl acetate copolymer or butylene terephthalate/polytetramethylene ether terephthalate. Use of silicon rubber or ethylene-vinyl alcohol depots are also contemplated.

Controlled release oral formulations are also well known. In one embodiment, the active complex is incorporated into a soluble or erodible matrix, such as a pill or a lozenge. In another example, the oral formulations can be a liquid used for sublingual administration. These liquid compositions can also be in the form a gel or a paste. Hydrophilic gums, such as hydroxymethylcellulose, are commonly used. A lubricating agent such as magnesium stearate, stearic acid, or calcium stearate can be used to aid in the tableting process.

Embodiments of the compositions described herein may be administered once, twice, or three times per day. In some aspects, the compositions are administered four times a day. For example, the compositions may be administered before, after, or during a meal. Dosing for oral administration may be with a regimen calling for single daily dose, or for a single dose every other day, or for a single dose within 72 hours of the first administered dose, or for multiple, spaced doses throughout the day. Active agents that can make up the therapy may be administered simultaneously, either in a combined dosage form or in separate dosage forms intended for substantially simultaneous oral administration. The active agents which make up the therapy may also be administered sequentially, with either active component being administered by a regimen calling for two-step ingestion. Thus, a regimen may call for sequential administration of the active agents with spaced-apart ingestion of the separate, active agents. The time period between the multiple ingestion steps may range from a few minutes to as long as about 72 hours, depending upon the properties of each active agent such as potency, solubility, bioavailability, plasma half-life and kinetic profile of the agent, as well as depending upon the age and condition of the patient. The active agents of the therapy whether administered simultaneously, substantially simultaneously, or sequentially, may involve a regimen calling for administration of one active agent by oral route and the other active agent by intravenous route. Whether the active agents of the therapy are administered by oral or intravenous route, separately or together, each such active agent will be contained in a suitable pharmaceutical formulation of pharmaceutically-acceptable excipients, diluents or other formulations components.

Active ingredients (e.g., maca root and other pharmaceutical or supplemental ingredients that may be present) can be administered by the oral route in solid dosage forms, such as tablets, capsules, and powders, or in liquid dosage forms, such as elixirs, syrups, and suspensions. Each active ingredient can be administered by the parenteral route in liquid dosage forms. The pharmaceutical composition is preferably made in the form of a dosage unit containing a particular amount of each active ingredient.

In general, the pharmaceutical dosage forms of compositions of this application can be prepared by conventional techniques, as are described in Remington's Pharmaceutical Sciences, a standard reference in this field [Gennaro A R, Ed. Remington: The Science and Practice of Pharmacy. 20^(th) Edition. Baltimore: Lippincott, Williams & Williams, 2000]. For therapeutic purposes, the active components of this combination therapy application are ordinarily combined with one or more adjuvants appropriate to the indicated route of administration. The components may be admixed with lactose, sucrose, starch powder, cellulose esters of alkanoic acids, cellulose alkyl esters, talc, stearic acid, magnesium stearate, gelatin, acacia gum, sodium alginate, polyvinylpyrrolidone, and/or polyvinyl alcohol, and then tableted or encapsulated for convenient administration. Such capsules or tablets may contain a controlled-release formulation as may be provided in a dispersion of active compound in hydroxypropyl methylcellulose. Solid dosage forms can be manufactured as sustained release products to provide for continuous release of medication over a period of hours. Compressed tablets can be sugar coated or film coated to mask any unpleasant taste and protect the tablet from the atmosphere, or enteric coated for selective disintegration in the gastrointestinal tract. Both the solid and liquid oral dosage forms can contain coloring and flavoring to increase patient acceptance. Other adjuvants and modes of administration are well and widely known in the pharmaceutical art.

The compositions disclosed herein can preferably be formulated with other active ingredients such as a slow-acting agent or long acting agent in addition to drugs or alone before meals and/or after meals. Effective doses may be extrapolated from dose-response curves derived from in vitro or animal model test systems. Such animal models and systems are well known in the art.

Example 1: Effects of Maca Compositions Under Inflammatory Conditions

Human peripheral blood mononuclear cell (PBMC) cultures were treated with the highly inflammatory bacterial lipopolysaccharide (LPS) from E. coli (positive control). The cultures were incubated for 24 hours, after which the cells and the culture supernatants were harvested and used to monitor the reactions in each culture. The supernatant from each culture was used for testing of a panel of pro- and anti-inflammatory cytokines and anti-viral chemokines, using a Luminex magnetic bead array and the MagPix® multiplexing system to test for selected cytokines, as shown in FIGS. 1-11.

The testing for cellular activation was performed such that all treatments, including each dose of test product and each positive and negative control, were tested in triplicate. The testing of cytokine production was tested in duplicate. The tests were performed on cells from one healthy blood donor.

Average and standard deviation for each data set, as well as statistical comparison, were calculated using Microsoft Excel. Statistical analysis of the in vitro data was performed by comparison of the measures (duplicates for Luminex cytokine testing) for a specific test condition to relevant controls. Tail: a two-tailed t-test was applied, because a test material may either induce or inhibit a specific assay outcome. Type: an independent, or ‘unpaired’, test was applied, because each cell culture is unique, positioned in different areas of a microplate with slightly different environmental exposures, and handling through the assay (such as pipetting), although uniform, was not identical. Statistical significance was indicated if p<0.05 and a high level of significance was indicated if p<0.01.

The effects of maca roots and blends on PBMC cytokine production were tested following the protocol described above. Below is a table listing the ten cytokines/chemokines, and a brief description of their major mode of action. Following this description are the results of the testing on PBMC culture supernatants and after administering doses of 0.5 mg/mL test product.

FIG. 10 represents the change in IL-2 levels in supernatants from PBMC cultures treated with serial dilutions of test products for 24 hours in the presence of bacterial lipopolysaccharide (LPS). Data are shown as group averages plus or minus the standard deviation from each duplicate data set, when compared to the average cytokine production from cultures treated with LPS in the absence of test products.

FIG. 11 represents the change in mitochondrial function in PBMC cultures treated with serial dilutions of test products for 24 hours in the presence of bacterial lipopolysaccharide (LPS). These PBMC cultures were exposed to six 4-fold serial dilutions of each product, starting at 2 mg/mL. Testing conditions were performed in triplicate and cultures maintained at 37° C. and 5% CO₂ for 24 hours. After the 24-hour incubation, cultures were processed in the colorimetric MTT assay. An MTT assay utilizes a dye that changes color dependent on mitochondrial function, which is directly related to cellular metabolic activity and viability. Healthy cells metabolize the MTT dye and turn the cultures purple. When a reduction in color is measured, this is linked to reduced cellular viability, either as a result of direct killing, or inhibition of mitochondrial function leading to cell death. In this case, a measured increase in color is measured, which indicates an increased mitochondrial function (energy production) because unstimulated PBMC do not undergo cell division in the 24-hour period and the increased colorimetric reading observed in several maca-treated cell cultures are likely linked to direct effects on cellular energy production. Data are shown as group averages plus or minus the standard deviation from each duplicate data set, when compared to the average cytokine production from cultures treated with LPS in the absence of test products.

These results demonstrate that compositions comprising both 4:1 black maca root to red maca root and 1:1 black maca root to yellow maca root possess significant anti-inflammatory effects. For example, but not limited to, reduction of IL-6 (0.02 g), IL-8 (both 0.5 and 0.02 g/L), and reduction of IL-1β were all stronger than for either black or red maca root alone. Such results were not expected or predicted.

Example 2: Effects of Maca Compositions on Inflammation

A double-blind, randomized, parallel group dose-finding pilot study is conducted to compare a dose of an appropriate amount of a maca composition per day as a daily regimen to a placebo control in 40 outpatients (mean age 30; half females, half males) with diagnosed chronic inflammation and/or an autoimmune disease, disorder, or condition. The compositions may, for example, include a predetermined amount of maca per kg of a subjects' body weight. Subjects are required to have exhibited symptoms of chronic inflammation and/or an autoimmune disease, disorder, or condition for at least six months prior to initiating the trial, and may not have commenced any new medications within six months of initiating the trial.

The subjects are divided into groups of eight, Groups A, B, C, D, and E. Group A is the control group, Group B receives yellow maca only, Group C receives 1:1 black to red maca, Group D receives 4:1 black to red maca, and Group E receives 1:1 black to yellow maca. Blood samples are taken from each subject at week 0, week 1, week 4, week 8, week 12, and week 16. Cytokine levels are measured in each sample. At each blood draw, subjects also complete a brief questionnaire regarding their symptoms.

Subjects in each group report mild to moderate alleviation of symptoms, with subjects in Group B reporting similar results to control Group A. Subjects in Groups C, D, report the most improvement in symptoms relative to Groups A and B, with subjects in Group D reporting the greatest improvement. Similarly, Groups C and D also have the largest decrease in cytokine levels, particularly in IL-6 levels.

Example 3: Effects of Maca Compositions on Libido and Sexual Function

A double-blind, randomized, parallel group dose-finding pilot study is conducted to compare a dose of an appropriate amount of a maca composition per day as a daily regimen (relative to placebo control) in 40 outpatients (mean age 36; 17 females) with diagnosed sexual dysfunction. The compositions may, for example, include a predetermined amount of maca per kg of a subjects' body weight. Subjects are required to meet at least one of the following criteria for at least 4 weeks: (1) inability to have an orgasm (anorgasmia) during sexual activity; (2) clinically significant orgasm delay with masturbation or intercourse that, according to self-report, representing a meaningful delay and interfering with sexual function compared with the subject's usual time to achieve orgasm; (3) inability to attain or maintain until completion of sexual activity an adequate erection or lubrication swelling response of sexual excitement that, according to self-report, interfered with sexual function compared to prior to antidepressant medication; (4) decreased libido according to self-report.

Exclusion criteria include: primary or prior diagnosis of a sexual disorder; sexual dysfunction secondary to general underlying medical condition; no other current primary psychiatric disorder; alcohol or substance abuse or dependence within the past 6 months; recent major sexual relationship changes, disruption, or turmoil ongoing or anticipated which are unrelated to their sexual dysfunction, HAM-D-17 or HAM-A score (either) >10; current use of other drugs for sexual dysfunction or other therapies or medications to treat sexual dysfunction; hormone replacement therapy, unless patient had been on stable dose of hormone therapy for at least 3 months prior to the antidepressant treatment, had no sexual dysfunction while on the same hormone therapy regimen, and there was no change in the hormone replacement therapy during the study; pregnancy, lactation, or plans to become pregnant during the study; any clinically significant abnormality of the screening physical examination; any medical or psychological condition or social circumstances that would impair subject's ability to participate reliably in the study, or that may have increased the risk to subjects or others as a result of participating in the study; testosterone implant during 6 months prior to screening; receiving psychosexual or other therapy for sexual dysfunction and not willing to discontinue that treatment at screening; and/or subjects for whom sexual activity was inadvisable.

The subjects are divided into groups of eight, Groups A, B, C, D, and E. Group A is the control group, Group B receives yellow maca only, Group C receives 1:1 black to red maca, Group D receives 4:1 black to red maca, and Group E receives 1:1 black to yellow maca. The Arizona Sexual Experience Scale (ASEX) and the Massachusetts General Hospital Sexual Function Questionnaire (MGH-SFQ) are used to measure sexual dysfunction. Subjects in Group B report similar results to control Group A. Subjects in Groups C, D, report improved sexual function and libido relative to Groups A and B, with subjects in Group D reporting the greatest improvement.
